StandardsAxial cylindrical roller bearings according to DIN 722 (series 811
and 812) The versions 813, 814, 874, 893, and 894 are not
standardied.

TolerancesRunning, design and dimension tolerances of axial cylindrical
roller bearings are equivalent to the axial bearings standard
tolerances, see section bearing data. Axial minimum load Axial
cylindrical roller bearings have always to operate under axial load
to avoid any slip between rollers and bearing washers. If external
load is too small, you may use springs to achieve a pre-stress of
the bearing. The minimum axial load is calculated as follows:
